You can now grab lemmur from f-droid and the Play store.
If you want to follow lemmur releases/news checkout the repo and/or follow the !lemmur@lemmy.ml community. You can always support the development on Patreon or BuyMeACoffee
PS. We do not flavor our releases: github release tab, fdroid, and play store apks are built from the same source code. Feel free to download lemmur from any place you like.
Just installed it, works great!
